trouble binding to <next> & <prior>

trouble binding to <next> & <prior>

[Mirko]

Hello,

I have a following keybinding, parts of which do not work.  In
particular I am trying to bind view-previous-entry to the page-up key
on the standard PC keyboard (using Emacs 22.1).  I used both h-k and h-
l to determine that this key is identified with "<prior>" & <next>".

(defvar iop-alert-mode-map nil
  "Keymap for IOP-alert mode")
(unless iop-alert-mode-map
  (setq iop-alert-mode-map (copy-keymap text-mode-map))
  (define-key iop-alert-mode-map (kbd "<prior>") 'view-previous-entry)
  (define-key iop-alert-mode-map (kbd "<next>") 'view-next-entry)
  (define-key iop-alert-mode-map (kbd "d") 'mark-entry-for-deletion)
  (define-key iop-alert-mode-map "m" 'mark-entry-for-save))

When in a buffer with iop-alert mode, doing h-m gives me the following
output on keybindings:
... stuff skipped
< n e		Prefix Command
< p r		Prefix Command
< n e x		Prefix Command
< p r i		Prefix Command
< n e x t	Prefix Command
< p r i o	Prefix Command
< n e x t >	view-next-entry
< p r i o r	Prefix Command
< p r i o r >	view-previous-entry

It seems <prior> and <next> are bound to the character sequence
"<prior>" and "<next>".  Pressing those characters will invoke the
commands.  But pressing the Page-up/down keys will not.

Indeed, doing a h-k shows that page-up/down are still bound to scroll
up/down.

What am I doing wrong?

Thank you,

Mirko

emacs-version   --> "22.2.1"
(kbd "<prior>") --> [prior]

if you don't get this vector with one symbol for (kbd "<prior>"),
indeed you have a problem.

I tried that, and I get exactly as you suggested.

It looks like you have been doing

  (define-key iop-alert-mode-map "<prior>" 'view-previous-entry)

instead of

  (define-key iop-alert-mode-map (kbd "<prior>") 'view-previous-entry)

Nope.  This is what I have

 (define-key iop-alert-mode-map (kbd "<prior>") 'view-previous-entry)

Could you try to re-evaluate the code. Place point inside the defvar and 
do C-M-x (this will just set iop-alert-mode-map to nil again). Then 
place point inside the unless form and do C-M-x again.

Does this correct the keymap?

Pascal is right: _something_ has bound "<prior>" in iop-alert mode.
Perhaps there is another library earlier in load-path, or an out-of-date
compiled version of the library.

For debugging purposes, you might try first to replace the
“(kbd "<prior>")” with just “[prior]”. If that still doesn't work, at
least you get rid of one possbibility of problem.

Also, simply try to bind something to the PageUp key, e.g.
(global-set-key (kbd "<next>") 'find-file)
and see if your emacs recognize that at all.

What build or platform is your emacs on?

Few monhts ago i tried “Emacs.app” (the emacs build for Mac OS X and
NeXTStep, based on cacoa), it has a known bug that it won't recognize
keybindings on the numerical keypad. The author said he doesn't know
what's the problem or how to fix. (“Emacs.app” has several major bugs
that i couldn't adapt it as my emacs. The oher one is unicode ...)

OK, there were a couple of problems:

1) old *.elc file
2) I was creating a derived mode
3) Outside of the define-derived-mode expression, I was separately
using the construct:
(unless iop-alert-mode-map
  (setq iop-alert-mode-map (copy-keymap text-mode-map))
 (define-key iop-alert-mode-map (kbd "<prior>") 'view-previous-entry)
...

So, what was happening most likely was that the derived mode was
creating the mode-map, and this prevented the (unless iop-alert-mode-
map  from operating.

I moved the define-key inside the define-derived-mode expression.

Thank you all for putting up with this.

Yes and no.

Following your instructions to the keystroke, I first set the map to
nil, and then re-assigned it.  And now h-m gives a much saner
response:
<next>		view-next-entry
<prior>		view-previous-entry

(In my defense, I did try restarting emacs and reloading the file,
before starting this topic).

However, h-k on page up and page down still gives:
<next> runs the command scroll-up
  which is an interactive built-in function in `C source code'.
It is bound to C-v, <next>.
(scroll-up &optional arg)

??

Thanks,

Mirko

That is good.

Just a short note to avoid confusing other readers: I think you mean 
`C-h m' here when you write `h-m'. And below you probably mean `C-h k'.

Did you happen to compile the file? The compiled file takes precedence 
over the uncompiled. This is confusing and I have fallen in that trap 
myself. (There is a warning in the *Message* buffer but that is a bit to 
shy in my opinion.)

There are many keymaps involved. You can use `C-h b' to see all the key 
bindings.

There is rather much in the manual describing this, for example

   (info "(elisp) Searching the Active Keymaps")
